A JTextArea is a multi-line area that displays text.

With JScrollPane, it's easy to be a scrollable text area, for example:

var ta:JTextArea = new JTextArea();
var sp:JScrollPane = new JScrollPane(ta);

`var columns:Int`

A number of columns in this JTextArea, if it changed then call parent to do layout.

If columns is set to zero or min than zero, the preferred width will be matched just to view all of the text.

`var horizontalBlockIncrement:Int`

The block value for the Horizontal scrolling.

`var horizontalUnitIncrement:Int`

Returns the unit value for the Horizontal scrolling.

`var rows:Int`

A number of rows in this JTextArea, if it changed then call parent to do layout.

If rows is set to zero or min than zero, the preferred height will be matched just to view all of the text.

`var verticalBlockIncrement:Int`

The block value for the Vertical scrolling.

`var verticalUnitIncrement:Int`

The unit value for the Vertical scrolling.

`var viewPosition:IntPoint`

The view's position.

It returns (0,0) if view is null.

@see setViewPosition to set view position loudly (to trigger events). @see Viewportable.setViewPosition

`function new(?text:String = '', ?rows:Int = 0, ?columns:Int = 0): Void`

`function addStateListener(listener:Dynamic ->Void?priority:Int = 0, ?useWeakReference:Bool = false): Void`

Add a listener to listen the viewpoat state change event.

When the viewpoat's state changed, the state is all about:

viewPosition
verticalUnitIncrement
verticalBlockIncrement
horizontalUnitIncrement
horizontalBlockIncrement

@see org.aswing.event.InteractiveEvent#STATE_CHANGED

listener	the listener
priority	the priority
useWeakReference	Determines whether the reference to the listener is strong or weak.

`function removeStateListener(listener:Dynamic ->Void): Void`

Removes a state listener. @see org.aswing.event.AWEvent#STATE_CHANGED

listener

the listener to be removed.

`function scrollRectToVisible(contentRect:IntRectangle, ?programmatic:Bool = true): Void`

@see Viewportable.scrollRectToVisible

`function scrollToBottomLeft(): Void`

Scrolls to view bottom left content. This will make the scrollbars of JScrollPane scrolled automatically, if it is located in a JScrollPane.

`function scrollToBottomRight(): Void`

Scrolls to view bottom right content. This will make the scrollbars of JScrollPane scrolled automatically, if it is located in a JScrollPane.

`function scrollToTopLeft(): Void`

Scrolls to view top left content. This will make the scrollbars of JScrollPane scrolled automatically, if it is located in a JScrollPane.

`function scrollToTopRight(): Void`

Scrolls to view to right content. This will make the scrollbars of JScrollPane scrolled automatically, if it is located in a JScrollPane.
